LOS ANGELES — Southland temperatures will climb sharply Friday and Saturday and, together with strong winds, create an elevated danger of wildfire before dipping precipitously starting Sunday, National Weather Service
forecasters said today.

Highs are expected to be around 10 degrees above normal Friday and 15 degrees above normal on Saturday, said NWS meteorologists Rich Thomson and Dave Bruno in telephone interviews from their Southern California monitoring station in Oxnard. The higher-than-usual temperatures will manifest themselves chiefly along the coast and in the valleys, they said.

Thompson said the temperature spike would result from high pressure over the region combined with weak Santa Ana winds out of the northeast.

“Nothing too strong,” he said, describing the impending conditions as “nothing out of the ordinary” for this time of the year.

The heat combined with strong winds, including gusts of between 30 and 40 miles per hour in the San Gabriel Mountains, will create “elevated fire danger” through Saturday, according to a statement on the NWS website.

The high in downtown L.A. is expected to be 83 degrees today, 91 Friday, 92 Saturday and 83 Sunday, according to an extended forecast. Highs in Woodland Hills are expected to be 92 today, 98 Friday, 99 Saturday and 86 Sunday.

The NWS, meanwhile, reported not a record high but a record low for an October 4 — 36 degrees Wednesday in the Antelope Valley, breaking the record of 38 set in 2013.

Along the coast, elevated surf and strong rip currents are forecast beginning Friday and lasting through the weekend. Those conditions will result from a long-period south-southwest swell, they said.

A beach hazard statement, which is a notch less serious than a high surf advisory, will be in effect through Sunday in Orange County, where surf of 2- 3 feet is expected, according to the NWS.

The high surf and strong rip currents will create “an increased risk of ocean drowning. Rip currents can pull swimmers and surfers out to sea,” according to an NWS statement. “Large breaking waves can wash people off beaches and rocks and capsize small boats near shore.”

The NWS advised beach goers to always remain close to lifeguard stations when swimming.

The NWS forecast sunny skies in L.A. County today and highs of 74 in San Pedro; 75 in Torrance; 77 in Avalon, at LAX and on Mount Wilson; 83 in Downtown L.A., Long Beach and Lancaster; 84 in Palmdale; 85 in San Gabriel; 86 in Santa Clarita, Ontario, Rancho Cucamonga and Whittier; 87 in Pasadena, West Covina and Burbank; 88 in North Hollywood; 89 in Van Nuys; 91 in Northridge; and 92 in Woodland Hills.

In San Bernardino County today, it will be 68 in Big Bear and Running Springs; 81 in Hesperia; 82 in Victorville; 84 in Yucaipa; 89 in Redlands; and 90 in San Bernardino.

In Riverside County, it will be 87 in Temecula; 88 in Murrieta; 89 in Riverside, Menifee, Perris, Lake Elsinore and Hemet; 92 in Desert Hot Springs; 94 in Palm Springs; and 95 in Blythe, Palm Desert and Indio.

Sunny skies were also forecast in Orange County, along with highs of 72 in Newport Beach; 73 in San Clemente; 75 in Laguna Beach; 82 in Santa Ana; 83 in Irvine; 84 in Mission Viejo and Anaheim; and 86 in Fullerton and Yorba Linda.

L.A County highs will climb by up to 10 degrees Friday and remain at those levels Saturday before retreating by up to 12 degrees Sunday, a review of an extended NWS forecast indicates. Orange County temperature will increase by up to nine degrees Friday and fall by up to 12 degrees Sunday.
